A scientific investigation from the University of Warwick has found that charging your phone by induction could damage  its battery’s lifespan.

The researchers explained that wireless charging requires energy to be transmitted across an air gap, a process that necessarily generates some heat. The fact that the surfaces of the phone and charging pad must be in very close proximity means that the heat exposure will damage the phone’s lithium-ion battery life over time, as they are sensitive to being stored above 30 degrees Celsius.
